SHIP-GHIMNEY JACK.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, JOHN KINGSBOROUGH, of-Clev-eland, in the county of Cuyahoga, and Statexof Ohio,

have invented certain new and useful improvements in shipflhinineyiJacks; and I do hereby declarethat the making a part of'this specificatiom in which Figure 1 is a perspective view of the chimney jack. Figure 2 is a horizontal section of. the same. Figure 3'is a longitudinal section. Like letters of reference refer to like parts in, the difi'erent riews.

I A, fig. 1, represents the chimney jack, which is designed to be used on shipboard in order to prevent the smoke descending the chimney, as it is liable to do in the present mode of constructing them, from the different currents'of air to which a ship is subject. B B are slides or doors, which may be'opened or'closed at pleasure. C C, fig. 2, are deflectors or valves, pivoted to the ears a, fig. 3, so as to command the opening made by the slide B. These defieetors are hung so as to turn'with the current of air as it"strikes them. D are guards, for a purpose hereafter shown; they also form standards or braces. for supporting the upper part or cap of the chimneyjack, by connecting the upper piece I: to the lower piece e, which is directly connected to the chimney.

following is a full and complete description of the same, reference being had to the accompanying drawings,

,Should the wind blow in the direction-of the arrow cl, fig. 2, the slides toward that point'should be closed and the one opposite opened; this prevents the wind'entering the chimney directly, but in striking the sails it often glances downward and backward, forming an opposite current or eddy, which coming in contact with the chimney will enter throughtheopen slide. This current entering the largest opening a, impinges against the guard D, which has a tendency to throw it back against the chimneysside, and is carried around the channel or chamber I, by the force of the current entering the opening, and forced through thesmaller opening f; this also aids in carrying the smoke through. When the current ofair is in the direction of the arrow 9, it strikes the deflector and turns itin the direction of the clotted lines 72, thus forming the larger opening atf; and the smaller-at 2, coming against the guard D, which changes its course and iscarried around in the manner before described.

The case J may be made of any desirable. proportion to enlarge or decrease the size of the jack. When the ship is tacking, the wind coming from different points, &c., this chimney jack is found to be of great practical utility, as it can be easily adjusted to currents of air from any direction. hat I claim as my improvement, and desire to secure by LettersPateut, is p The slides B, adjustable hinged deflectors C, and guards D, in combination with the channel or chamber I, and case J, arranged in the manner and for the purpose set forth."
